MECHANISM FOR REGULATING WATCHES.

Specification of Letters Patent.

Patented Feb. 26, 1907.

To all whom it may concern.-

Be it known that I, RICHARD LANGE, a subject of the King of Saxony, and a resident of Glashutte, Kingdom of Saxony, in the German Empire, have invented a certain new and Improved Mechanism for Adjusting or Regulating Vvatches, of which the following is a full, clear, and exact description.

The present invention relates to 1nechan ism for adjusting or regulating watches, and consists, essentially, in providing means for adjusting the parts without having to shift the point of attachment of the hair-spring on the collet.

According to Jules Grossmanns theory the point or attachment on the collet should lie in a horizontal line passing through the balance center when the watch is in a sus pended position. It is, however, very often necessary to shift this point in varying the rate, in which case the rating of the watch is entirely disturbed. Any alteration of the point of attachment or the curve necessitates the re-regulation of the watch before it is possible to adjust the movement to position, thus causing considerable loss of valuable time.

According to the present invention, in order to facilitate the adjustment to positions the stud is constructed to allow of the adjustment of the same, together with the regulator, Without changing the angle of the parts as regards each other.

' In order to render the present specification easily intelligible, reference is had to the accompanying drawings, in which similar letters of reference denote similar parts throughout the several views.

Figure 1 is an elevation of a further modification having a micrometric regulator, Fig. 2 being a horizontal section through the line E F of Fig. 1, and Figs. 8, 4, and 5 elevations, respectively, of the micrometric regulator, the pointer, and stud-rings.

According to the present invention it is therefore not necessary to shift the inner point of attachment on the collet; but the collet may be turned as far as necessary for its proper adjustment to the hanging positions, whereupon the stud, together with the regulator, may be adjusted, the angle between these parts remaining constant. Thus the primary regulating of the movement is in no way influenced by this process, but rather the variance in the three vertical positions which has hitherto taken place is compensated.

The construction comprises three parts, to wit: the stud-ring a, having the arm a for the stud c, the nrcrometric regulator-ring r with the arm g with pins 8 s for the spring e, and the regulator-ring 1' with the pointer or hand h. 'l'he stud-ring a is split, sprung to the center part b of the cock f, movable onthereon and carries the two regulator-rings r r, mounted one above the other thereon, such rings also being split. T he regulatorring 1", having the pointer 7L and mounted between the cock and the ring 7', is provided with a screw i, by me ans of which it may either be clamped to the cock for be coupled to the regulator-ring 1*, in that the head of the said screw 'L is adapted to pass between the teeth or recesses at the periphery of the ring 7", Fig. 4, when the said screw is unscrewed or raised from the ring r so that its head can enter the said recesses. 'I'hese teeth or recesses are advantageously so disposed 011 the periphery of the ring 1" that by shifting the said ring one tooth a certain predetermined variation of the rate-for instance, one second a daywill be attained. Thus when the said screw is raised the angle between the arm 9 and the stud a may be varied at will. If the screw "L is adjusted by being screwed down to lock the ring 1" and pointer h to the cock f, the ring 1" will be released and may be adjusted, together with the pointer-ring a, to any desired position.

By this arrangement of the parts the advantages are attained that each of the two rings 1" and 9" may be moved separately and may be adjusted together 011 the ring a, while the ring (1 remains locked. When the proper position for the ring a has been found in adjusting the watch to positions, the ring r may be locked to the cock f by means of the screw i or any other suitable device.
